Additional 402(v) Disclosure The following amounts were deducted from / added to Summary Compensation Table (SCT) total compensation in accordance with the SEC-mandated adjustments to calculate Compensation Actually Paid (CAP) to our principal executive officer (PEO) and average CAP to our non-PEO named executive officers. The fair value of equity awards was determined using methodologies and assumptions developed in a manner substantively consistent with those used to determine the grant date fair value of such awards.
